Long service life due to triple spindle seal- Conical spindle seal: The seal 10 arranged at an angle of 45° effectively prevents the leakage of media when operating the spindle- O-ring: Stabilising spindle seal 21 with low wear and long service life - Pretensioned self-adjusting spindle seal: The spindle packing consists of several V-rings 11, a spring washer 13 and a stainless steel sleeve 12. The spring washer 13 ispretensioned via the spindle nut 14. The pretension force is distributed to the V-rings 11 via the stainless steel sleeve 12,thereby preventing the leakage of media. The pretension provides low maintenance and reliable spindle sealing even after along service life.

The spindle seal system


GEMÜ CONEXOThe interaction of valve components that are equipped with RFID chips and an associated IT infrastructure actively increaseprocess reliability.

Thanks to serialization, every valve and every relevant valve component such as the body, actuator or diaphragm, and even auto-mation components, can be clearly traced and read using the CONEXO pen RFID reader. The CONEXO app, which can be in-stalled on mobile devices, not only facilitates and improves the "installation qualification" process, but also makes the mainten-ance process much more transparent and easier to document. The app actively guides the maintenance technician through themaintenance schedule and directly provides him with all the information assigned to the valve, such as test reports, testing doc-umentation and maintenance histories. The CONEXO portal acts as a central element, helping to collect, manage and processall data.
